The invention relates to passive and non-invasive monitoring and report of a frozen liquid crystal display. A passive and non-invasive monitoring liquid crystal display (LCD) system includes a graphiccontroller configured to generate alternate driving command sets and forward the driving command sets to allow execution of a driving electronic device for activation of a display element on a display surface. An initial driving command set corresponding to the first frame enables the driving electronic device to draft a solid red-filling initial pattern to a selected region of the display surface. An alternate driving command set enables the driving electronic device to draft a contrast pattern, such as a solid cyan filler, to the selected region. It is assumed that the refreshing rate between the initial and alternate driving command sets is enough high, when the frozen initial and contrast patterns clearly and rapidly represent the stuck/frozen failed state, an operator can only sensethe integration of two pat
